TECHNICAL FIELD

The present invention relates to self propelled platforms for thetransport of tracked vehicles, and more specifically to self-propelledplatforms controllable by the driving controls of the tracked vehiclebeing transported.

BACKGROUND OF THE INVENTION

Tracked vehicles, such as earth movers, construction machinery, allterrain vehicles, and snowmobiles, are adapted to travel over rough andunstable terrain without becoming trapped or bogged down, but they arelegally forbidden from most paved highways. Tracked vehicles tend todamage pavement, and many of these vehicles cannot travel at minimumhighway speeds. For these reasons, tracked vehicles are usuallytransported to and from their sites of use on trailers. Typically, thetracked vehicle is carried on a tractor-towed flatbed trailer, or on aflatbed integrated into a truck body.

The transport of tracked vehicles on towed trailers or flatbed trucks isan extremely inefficient and wasteful transport system. The transportvehicle duplicates many of the costly systems of the tracked vehicle,particularly the power plant, and a fully equipped cab for a driver. Thetransport vehicle must carry its own fuel supply, and fuel consumptionis increased by the fact that the tractor must propel its own weight.When the tracked vehicle requires specialized operating skills, its crewmust also be accommodated either in the transport vehicle or in aseparate convoyed vehicle. There is a need for a system and method fortransporting a tracked vehicle that does not require a separateself-sufficient carrier vehicle.

The cargo tracked vehicle 30 is preferably a vehicle powered by a powerplant 40 generating an electrical output, preferably a gasoline ordiesel powered electrical generator. The power plant 40 of the cargotracked vehicle 30 charges at least one battery 42. During theindependent operation of the cargo tracked vehicle 30, the power plant40 and battery 42 serve as power sources for an electric motor (notshown) of the cargo tracked vehicle 30 to drive the tracks 44 of thecargo tracked vehicle 30. The cargo tracked vehicle 30 includes drivingcontrols of any suitable type known in the art, including a steeringcontrol 50, such as a steering wheel or joystick, a brake control 52,such as a brake pedal, propulsion control 54, such as an acceleratorpedal, and transmission control 56 such as a transmission selectorlever. During operation of the cargo tracked vehicle 30 independent ofthe wheeled mobile platform 12, these controls are used by the driver ofthe cargo tracked vehicle 30 to control the movements and otherfunctions of the cargo tracked vehicle 30 via driving systems, includinga steering system (not shown), a braking system (not shown) propulsionsystem (not shown) and a transmission system (not shown) of the cargotracked vehicle 30. These driving systems are powered by the electricalsystem (not shown) of the cargo tracked vehicle 30, which receives itspower from the power plant 40 and battery 42. Upon mounting of the cargotracked vehicle 30 upon the wheeled mobile platform 12, the power outputof the power plant 40 and battery 42 is disconnected from the electricalsystem (not shown) of the cargo tracked vehicle 30 and connected via apower conduit 48 to the electric motor 16 and electrical system 20 ofthe wheeled mobile platform 12. The driving controls of the cargotracked vehicle 30 are disconnected from the driving systems (not shown)of the cargo tracked vehicle 30 and operatively connected to the drivingsystems of the wheeled mobile platform 12, including the propulsionsystem 22, steering system 24, braking system 26, and transmissionsystem 28 of the wheeled mobile platform 12. The operative connectionsbetween the driving controls of the cargo tracked vehicle 30 and thedriving system of the wheeled mobile platform 12 are mediated bycontroller and feedback assemblies, which are described in detail below.A control and data conduit 74 is provided to serve as a physicalconnection to permit the flow of commands and information between thedriving controls of the cargo tracked vehicle 30 and the wheeled mobileplatform 12. Alternatively, the connection between the driving controlsof the cargo tracked vehicle 30 and the wheeled mobile platform 12 canbe mediated by any suitable wireless transmitters and receivers (notshown) known in the art. The redirection of power output and drivingcontrol from the cargo tracked vehicle 30 to the wheeled mobile platform12 can be accomplished by any switching mechanism known in the art,including mechanical disconnection and reconnection, and solid-stateelectronic switching.

Once power output and driving control have been redirected from thecargo tracked vehicle 30 to the wheeled mobile platform 12, the powerplant 40 and battery 42 serve as sources of electrical power to theelectric motor 16, which powers the drive wheels 14 of the wheeledmobile platform 12. The power plant 40 and battery 42 also provideelectrical power to the various systems of the wheeled mobile platform12 via the electrical system 20 of the wheeled mobile platform 12. In analternative configuration (not shown), at least one battery 42 can besituated in the wheeled mobile platform 12. The specific properties ofthe battery 42 are selected according to the voltage, power, andendurance requirements of the particular cargo tracked vehicle 30 andmobile wheeled platform 12 to which the present invention is applied.

The electric motor 16 can include any electric motor of suitable poweroutput and appropriate size and weight to propel a particularcombination of wheeled mobile platform 12 and cargo tracked vehicle 30.Preferably the electric motor 16 includes a wire-wound rotor with selfcleaning contact rings, because it eliminates the need for the rare andstrategic composition neodymium. The power plant 40 and the battery 42are electrically connected to the electric motor 16 by means of anelectrical controller 46, which regulates power output to the electricmotor 16. The power plant 40 and the battery 42 are also electricallyconnected to the electrical system 20 of the wheeled mobile platform 12,preferably through an electrical power distributor 47, which distributeselectrical power to the all other systems of the wheeled mobile platform12, including the propulsion system 22, a steering system 24, a brakingsystem 26, a transmission system 28. In the embodiment shown in FIG. 3,the battery 42 and electrical controller 46 are situated within thecargo tracked vehicle 30 and the electrical power distributor 47 issituated within the wheeled mobile platform 12, but any alternativesituation of these devices is possible. For example, the battery 42 andelectrical controller 46 can be situated within the wheeled mobileplatform 12 (not shown).

Preferably, the driving systems of the wheeled mobile platform 12 arecontrolled by the same steering control 50, brake control 52, propulsioncontrol 54, and transmission control 56 utilized to control the cargotracked vehicle 30 during its independent operation. Alternatively, oneor more separate controls (not shown) situated in the cargo trackedvehicle 30 can be reserved for the control of one or more drivingsystems of the wheeled mobile platform 30.

The present invention includes controller assemblies operativelyconnecting the controls of the cargo tracked vehicle 30 to thecorresponding driving systems of the wheeled mobile platform 12, toenable a driver housed in the cargo tracked vehicle 30 to drive thewheeled mobile platform 12. That is, the controller assemblies of thepresent invention enable a driver housed in the cargo tracked vehicle 30to control at least one of the driving systems, and preferably all ofthe driving systems, of the wheeled mobile platform 12. The controllerassemblies are indicated as numbered solid connecting lines in theschematic shown in FIG. 3. The controller assemblies include a steeringcontroller assembly 58, a propulsion controller assembly 60, a brakingcontroller assembly 62, and a transmission controller assembly 64. Forat least a subset of the driving systems of the wheeled mobile platform12, the present invention also includes feedback assemblies to providereal-time information about the performance of each driving system tothe driver of the cargo tracked vehicle 30. The feedback assemblies,indicated as numbered dotted connecting lines in FIG. 3, include atleast a braking feedback assembly 66, a steering feedback assembly 70,and a transmission feedback assembly 72. In the preferred embodiment,each controller assembly transmits commands from a driving control ofthe cargo tracked vehicle 30 to the corresponding driving system of themobile wheeled platform 12 in the form of electrical signals transmittedvia a wired control link. Each feedback assembly transmits data in theform of low-current electrical signals also transmitted via a wired datalink. The wired command and data links are carried by a control and dataconduit 74. Alternatively, commands and data can be transmitted betweenthe cargo tracked vehicle 30 and wheeled mobile platform 12 by anysuitable combination of wireless transmitters and wireless receiversknown in the art.

In the preferred embodiment of the present invention, the controllerassemblies are generally characterized as “drive by wire” controlassemblies well known in the art. A controller assembly suitable for thepresent invention includes a sensor (not shown), to continually sensethe driver's adjustment of a driving control; a servo controller (notshown), usually integrated with the sensor, to process data produced bythe sensor and accordingly generate electronic commands; and a servomotor (not shown) situated in the wheeled mobile platform 12, to receivethe electronic commands and translate them into adjustments oractuations of a device in the wheeled mobile platform 12. Examples ofspecific assemblies are provided below.

A control and data conduit 74 is provided to carry the wiring of thecontroller and feedback assemblies between the cargo tracked vehicle 30and the wheeled mobile platform 12. In the preferred embodiment, thepower conduit 48 and the control and data conduit 74 are incorporated ina unitary connecting conduit 76 extending from an outlet (not shown) ofthe cargo tracked vehicle 30 and terminating in a plug (not shown)mateable with a complementary receptacle (not shown) of the wheeledmobile platform 12. A unitary connecting conduit 76 facilitates therapid interconnection and disconnection of the cargo tracked vehicle 30to the wheeled mobile platform 12. Alternatively, any suitablecombination of wiring and interconnection modes can be employed toconnect the tracked vehicle 30 to the platform 12.

The steering controller assembly 58, best shown in FIG. 4, operativelyconnects the steering control 50 of the cargo tracked vehicle 30,preferably a steering wheel or joystick, to the steering system 24 ofthe wheeled mobile platform 12. In the preferred embodiment, thesteering controller assembly 58 includes a steering motion sensor 84mechanically engaged to a steering shaft 86 movable by the steeringcontrol 50. The steering motion sensor 84 communicates with a steeringservo controller 88. The steering servo controller is connected to asteering servo motor 90 situated in the wheeled mobile platform 12, theconnection preferably being mediated by steering control wiring 92extending through the control and data conduit 74.

In operation, the steering motion sensor 84 collects data on the motionsof the steering shaft 86, the steering servo controller 88 translatesthe data into electronic commands, and the steering control servo motor90 translates the commands into forceful motion of a servo motor shaft94. The servo motor shaft 94 is operatively engaged to a pinion gear 98engaged with a rack gear 100 housed in a steering gearbox 102. Themotion of the servo motor shaft 94 rotates the pinion gear 98 to causethe lateral motion of the rack gear 100. The lateral motion of the rackgear 100 is transmitted by a tie rod assembly 104 to produce causeangular movements of a steerable road wheel 18. Alternatively, thesteering gearbox 102 includes a worm gear drive (not shown) or anysteering gear assembly known in the art that can be operated by a rotaryservo motor. Any suitable alternative mechanical linkage can also beemployed to connect the steering servo motor 90 to the steerable roadwheel 18.

The steering feedback assembly 70 includes asteering motion sensor 106 to sense the angular position and angularvelocity of at least two steerable road wheels 18. The steering motionsensor 106 communicates with a steering feedback servo controller 108,which processes data produced by the steering motion sensor 106 andaccordingly generates electronic commands. A steering resisting servomotor 110, operatively engaged to the steering shaft 86 of the trackedvehicle 30, applies resisting torque to the steering shaft 86 inaccordance with the electronic commands generated by the steeringfeedback servo controller 108. The steering feedback servo controller108 is connected to the steering resisting servo motor 110 by steeringfeedback wiring 112 extending through the control and data conduit 74.Alternatively, steering resistance can be provided by any suitableresisting means known in the art. In an example of operation, thesteering feedback servo controller 108 commands the steering resistingservo motor 110 to exert resisting torque on the steering shaft 86 ininverse proportion to the angular velocity of a steerable road wheel 18,so that the steering wheel 50 is more difficult for a driver to rotateearly in the course of a turn than later in the course of the turn.

Electrical power to operate the steering control assembly 58 andsteering feedback assembly 70 is preferably provided by the power plant40 and battery 42 via the electrical system 20 of the wheeled mobileplatform 12.

The propulsion controller assembly 60 of present invention, best shownin FIG. 5, operatively connects the propulsion control 54 of the cargotracked vehicle 30, such as a conventional accelerator pedal, to theelectrical controller 46 of the power plant 40 and battery 42, toregulate the voltage delivered to propulsion system 22 of the wheeledmobile platform 12. The propulsion system 22 of the wheeled mobileplatform 12 includes at least an electrical motor 16. Specifically, thepropulsion control 54 is operatively connected to a variable sensor 114,which is adjustable according to the position of the propulsion control54. The variable sensor 114 transmits signals to the electricalcontroller 46 of the power plant 40 and battery 42, to regulate theamount of electrical power the electrical controller 46 delivers to theelectric motor 16. Optionally, the connection between the electricalcontroller 46 and the electric motor 16 can be made via the electricalpower distributor 47 (not shown). A propulsion feedback assembly (notshown) includes at least any suitable speedometer known in the art totransmit the speed of at least one road wheel 13 to a speedometer (notshown) situated in the cargo tracked vehicle 30.

The braking controller assembly 62, best shown in FIG. 6, operativelyconnects the brake control 52 of the cargo tracked vehicle 30 to thebraking system 26 of the wheeled mobile platform 12. The braking system26 includes at least a master cylinder 128, a hydraulic circuit 134 influid communication with the master cylinder 128 and with at least onebrake actuator 130, which is operatively connected to a brake 132. Thebraking controller assembly 62 transduces a driver's pressure on a brakepedal or other brake control 52 into a corresponding braking action uponleast two road wheels 13 of the wheeled mobile platform 12.

In the preferred embodiment, the braking controller assembly 62 includesa brake control pressure sensor 116 mechanically linked to the brakecontrol 52, to sense pressure on the brake control 52. The brake controlpressure sensor 116 communicates with a brake servo controller 118connected to a brake servo motor 120 situated in the wheeled mobileplatform 12, the connection being made by brake control wiring 122extending through the control and data conduit 74. In operation, thebrake control pressure sensor 116 collects pressure data from the brakecontrol 54; the brake servo controller 118 processes the data andtranslates it into electronic commands; and the brake servo motor 120translates the commands into forceful motion of a brake servo motorshaft (not shown). The brake servo motor shaft (not shown) isoperatively engaged by means of a linkage 124 with the plunger 126 of amaster cylinder 128 of any suitable type known in the art. The linkage124 is preferably a cam type linkage that converts the rotary motion ofthe brake servo motor shaft 122 into a corresponding linear movement ofthe plunger 126 into the master cylinder 128, to exert pressure onhydraulic fluid within the master cylinder 128. The master cylinder 128is in fluid communication with at least one brake actuator 130 of abrake 132 by means of a hydraulic brake circuit 134. The brake 132 ismounted on a road wheel 13. The plunger 126 is engaged to a plungerreturn spring (not shown) to maintain the plunger 126 in a restingposition in the absence of force from the brake servo motor 120. Inoperation, the driver's pressure on the brake control 54 induces acorresponding rotary movement of the brake servo motor shaft (notshown), causing the plunger 126 to pressurize the hydraulic circuit 134to exert force on the brake actuator 130, which presses the brake 132against the road wheel 13. When the driver's pressure on the brakecontrol 54 is released, the force of the return spring (not shown)returns the plunger 126 to its resting position and allows the brakeactuator 130 to release the pressure of the brake 132.

The brake actuator 130 can include the brake piston (not shown) of adisc brake or the brake cylinder (not shown) of a drum brake. Thebraking controller assembly 62 is powered by the electrical system 20 ofthe wheeled mobile platform 12. Preferably, the brake servo motor 120 issufficiently powerful to amplify the driver's pressure on the brakecontrol 54 to stop the wheeled mobile platform 12 without need ofauxiliary power boosters or other accessories.

In the preferred embodiment, the present invention also includes abraking feedback assembly 66 to provide a driver with tactileinformation the amount of braking force exerted in real time. Thebraking feedback assembly 66 includes a braking sensor 136 to sensechanges in hydraulic pressure within the braking system, preferably bysensory connection to the interior of the master cylinder 128; a brakingfeedback controller 138 communicating with the braking sensor 136, toconvert the data into electronic commands; and a brake resisting device140 operatively engaged to the brake control 52. In operation, increasedpressure within the master cylinder 128 causes the braking feedbackcontroller 138 to command the brake resisting device 140 to increase theresistance of the brake control 52 against pressure exerted by thedriver. The brake resisting device 140 can produce resistance by meansof hydraulic or magnetic force against the brake control 52, or by anysuitable pressure resisting mechanism known in the art.

The present invention includes a transmission 28 and a transmissioncontroller assembly 64. Preferably, the transmission 28 includes only afixed gear ratio and a neutral free wheel mode, with variations intorque and speed provided by the electric motor 16 itself.Alternatively, the transmission 28 is an automatic transmission as bestshown in FIG. 7, including a gear set 144, which is engaged to a finaldrive 148 to deliver power to at least two drive wheels 14. Thetransmission 28 is also preferably an electronically controlledtransmission regulatable by a transmission control unit 150 of a typewell known in the art,

The transmission controller assembly 64 includes a shift selector 154situated within the cargo tracked vehicle 30; a shift lever sensor 156,which senses changes in the position of the shift selector 154, and ashift controller 158 in communication with the shift lever sensor 156.The shift controller 158 processes changes in position of the shiftselector 154 into signals encoding a selected shift of gears. Thesignals are transmitted via one or more transmission control wires 160to the transmission control unit 150, where the signals are integratedinto the overall control output of the transmission control unit 150 toproduce gear shifts corresponding to the settings on the shift selector154. The driver-selected gear settings can include including a pluralityof forward speeds, neutral gear, reverse gear, and parking gear.

The present invention also includes a transmission feedback assembly 72to inform a driver of the current transmission setting. The transmissionfeedback assembly 72 includes transmission feedback wiring 162 totransmit transmission status signals from the transmission control unit150 to gear position indicator 164 visible to the driver of the cargotracked vehicle 30 and wheeled mobile platform 12.
